摘　　要：冷却塔风机是整个冷却水系统的核心设备,其运行状况直接关系到系统性能与能耗状况。本文针对国内某办公建筑的冷却塔风机运行状况进行实测,从风机与变频器电耗、冷却塔效率、冷机COP,设备寿命与运行策略的可行性4个方面分析评价了风机运行模式和策略对能耗的影响。Cooling tower fan is the core piece of equipment in cooling water system, which influences the system performance and the energy consumption significantly. In this paper, an experiment for the operation performance of a cooling tower fan was carried out from the following aspects, energy consumption of fan and inverter, cooling tower efficiency, COP of the chiller and the feasibility of equipment life and operation strategies. As a result, the influences of operation modes and control strategies on energy consumption were discussed.

关 键 词：冷却塔风机 运行模式 控制策略
